Modem Operating Modes

The iR1200 provides the following data connection modes:
•
Packet Data: A wireless modem connection used for accessing the Internet, sending
and receiving e-mail, and transferring small files over the packet data network using
standard IP protocols.
Data is sent in packets (blocks) of data at high speed, with the user being charged on
a per byte basis. After the transmission is completed, the user can remain connected
indefinitely without being charged for the idle time.
•
Circuit data: A wireless modem connection for sending and receiving data (faxes,
files, etc.) over the circuit-switched cellular channel, providing a direct point to
point connection with the destination device. The user is charged for the connection
time in minutes regardless of the amount of data transmitted.
